Abstract: 1,095,474. Injection moulding rubber articles. DUNLOP CO. Ltd. Sept. 18, 1964 [Oct. 5, 1963], No. 39312/63. Heading B5A. Articles of rubber or like elastomeric material are made by (i) injecting rubber &c. into a mould 60, 61 (Fig. 1), (ii) moving the mould and injection apparatus 1 apart in a direction parallel to the plane of their engaging surfaces so as to shear the rubber &c. in the mould inlets 63, (iii) removing the articles from the mould, and (iv) removing the rubber &c. from the inlets 63 by applying fluid pressure thereto. Mould filling.-The mould 60, 61 is moved into contact with the injection cylinder 1a by an hydraulic ram 9, operation of a limit switch 15 starting an injection screw 7. When the mould is full the pressure produced by the screw moves the mould downwardly through 0À005 inch thereby operating the switch 15 to stop the screw 7 and start a timer. The ram 9 then raises the mould again to ensure full closure thereof. The timer then causes the mould to be lowered again. When the mould has moved 0À04 inch a switch 16 is operated and downward movement is stopped. The injection apparatus 1 is as described in Specification 1,090,408. Sprue shearing.-Operation of switch 16 also energizes a pneumatic cylinder and piston 11, 13 to move the mould laterally on to a plate 14, thereby shearing the rubber in the inlets 63 level with the top surface of the mould. Article removal.-After vulcanizing in a vulcanizing press (not shown) the mould is placed on a plate 19 (Fig. 4). A piston and cylinder assembly 22 is actuated to raise a platen 23 carrying rods 25. The rods 25 pass through holes 76 in the bottom mould part 61 and are received in recesses 77 in the top mould part 60 which is thereby lifted to the dotted line position in Fig. 4. A block 27 carried by the platen 23 passes through an opening 28 in the plate 19 and raises a plate 67 carrying ejector pins 68. The moulded plugs 74 are thereby ejected from the mould cavities and are subsequently removed by a brush 29 moved across the upper face of the lower mould part 61. Sprue. removal.-The upper mould part 60 is moved from the dotted line position shown in Fig. 4 to a sprue removal station by means of a carriage 31 slidable on guides 40 by pneumatic cylinder and piston assemblies 37, 39. The mould part 60 is then raised by an hydraulic piston 41 and the rubber " pips " 75 in the mould inlets 63 are removed by intermittent blasts. of compressed air. This air is introduced by a pipe 45 into a chamber formed by the mould part 60, a seal 44 and a plate member 32 carried by the piston 41. A restrictor plate 48 spaced slightly from the upper surface of the mould part 60 is removed when the " pips " have all been loosened to allow the loosened " pips " to be blown away.

Abstract: 1,264,209. Semi-conductor memory elements. WESTINGHOUSE ELECTRIC CORP. 9 April, 1969 [19 April, 1968], No. 18135/69. Heading H1K. In a memory element comprising a dielectric disposed between a semi-conductor body and a metal electrode, the dielectric is capable of storing charges injected from the body or electrode so that the graph of net charge versus electrode-semi-conductor voltage exhibits a reproducible hysteresis loop. The preferred embodiment consists of a silicon IGFET, the gate insulation of which consists of a silicon nitride layer superposed on a layer of silica, with a further silica layer between the nitride and the electrode if desired. Alternative dielectrics are a single layer of silicon nitride or of a mixture of oxide and nitride, a layer of silica and alumina preferably coated with silicon nitride, or for operation at liquid nitrogen temperatures, a single layer of tantalum oxide. With gate voltages below a threshold level the preferred IGFET behaves conventionally but at higher voltages carriers tunnelling from the silicon to the dioxide-nitride interface are captured in deep traps in the nitride to provide the hysteresis effect. At normal temperatures the charges can be stored for several months, but can be removed by application of a reverse voltage above a threshold value or by irradiation. The insulating layers which should be amorphous or monocrystalline may be prepared by pyrolytic deposition though the oxide may instead be thermally grown. Aluminium is the usual gate electrode metal though a transparent tin oxide layer is preferred where irradiation erasure is to be used. In alternative embodiments the charge storing dielectric is disposed over the collector junction of a bipolar transistor to control its amplification or over the junction of a diode to control its breakdown voltage.

A laminated heat insulating article is produced by conveying a section or continuous sheet of material such as flat or corrugated galvanized steel or asbestos cement horizontally, its surface to be positioned remote from a heat source uppermost, delivering continuously to the moving surface superimposed laminations of aluminium foil and clear or transparent polyethylene film and applying heat and pressure to the assembly of the section, foil and interposed film by conveying it under a weighted flexible sheet and past heating means. The article is used as a roofing material, wall cladding or ducting or in the form of tiles. Apparatus for producing the laminated article comprises a frame 10, 11, 12 and 40, rollers 13 and 41 and bars 42 for supporting a continuous sheet 14 of, e.g. corrugated steel, a roll 17 of polyethylene bearing upon a counter-rotating roll 18 of Al foil to provide via pinch rollers 22 and a spring- loaded tensioning roller 28 superimposed film and foil for laminating with the steel sheet at forming rollers 33, a series of gas burners 43 providing a profiled flame for uniform heating of the corrugated assembly, a flexible sheet 49 of glass cloth weighted by gravel 54 for applying pressure to the assembly, pressure rollers 57 and a guillotine (not shown) for cutting the finished sheet into appropriate lengths. When the foil and film are applied to the corrugated sheet, the foil protrudes at one side beyond the edge of the sheet and the film also protrudes but to a lesser extent, these extending sections eventually being cut away by a trimmer 55. At the other side of the sheet a part thereof is left exposed (Fig. 5, not shown). One side of the flexible sheet 49 is engaged by a clamp bar suspended under a longitudinal channel to lift this side of the sheet clear of the laminations in theevent of a stoppage. The roll 17 and upper roller 22 may be frictionally braked by means of weights 26 and the roll 17 may also be provided with an electrically operable brake, in the circuit of which are connected solenoid valves 48 for control of the burners 43. The apparatus may be modified for applying the laminations to corrugated asbestos cement panels by replacing the rollers 13 with an endless belt 60 on which panels may be manually or mechanically placed and replacing the gas burners by downwardly directed electric or gas radiant heaters. The shaped forming and pressure rollers 33 and 57 are replaced by plain rollers if flat panels are to be insulated.
